    • Substituted 5'-nonanol/5'-nonene compounds which exhibit important antimicrobial and antifungal activity, compositions and methods of delivery against pathovars and pathogens, and methods of synthesis from commonly available reactants. The antimicrobial composition active ingredient is one or more substituted 1,2-alkylidenedioxybenzene compounds of the formula: ##STR1## where R.sub.3 is selected from 5'-nonanol and 5'-nonene, and R.sub.1 and R.sub.2 are selected from H and C.sub.1 -C.sub.5 alkyl, alkenyl and alkynyl groups. The preferred compounds are 5-(5'-hydroxy- 5'- nonanyl)-1,1-methylenedioxybenzene and 4-(5'-non-4'-enyl)-1,2-methylenedioxybenzene. Compositions including these compounds exhibit antimicrobial activity against a variety of pathogens and pathovars, e.g., Xanthomonas campestris spp. bacteria, antifungal activity against a variety of fungi and bacteria, and are highly specific, e.g., having antifungal activity against wheat powdery mildew and cucumber downy mildew, but do not affect seed germination or have appreciable herbicidal or insecticidal activity. Methods and compositions for delivery of these agents against such pathogens, and methods of chemical synthesis of the compounds are disclosed.

    • The invention provides a new process for the manufacture of aromatic compounds which at least once contain a benzene ring of an aromatic carbocyclic ring system bonded by an ethylene double bond in conjugation with a further aromatic ring system, i.e. contain the stilbene skeleton or stilbene analogon as central structural element, as well as certain classes of new compounds of this type. The process is characterized by the reaction of a Schiff base of an aromatic aldehyde with an aromatic carbocyclic six-membered ring compound which contains one to four methyl groups bonded to ring carbon atoms of a benzene ring, which furthermore contains aromatic rings which are exclusively six-membered carbocyclic rings, and wherein those benzene rings whose methyl groups are to be caused to react are free of other substituents which contain atoms wich are replaceable by alkali metal. The reaction is carried out in the presence of (a) a strongly basic alkali compound and (b) an N-dialkyl-acylamide as solvent. The compounds obtainable according to this process show a marked fluorescence emission and therefore are suitable for all purposes where fluorescence properties are used, as for instance optical brighteners, scintillators fluorescence dyes, etc.
